Having trouble keeping track of your advertising and reciprocal links? Link CheckUp makes it easy! You can monitor Web sites that you have exchanged links with, or purchased links from, to make sure that the sites are still linking back to your site. Advertising on other Web sites and building link partnerships is an effective means of driving more traffic to your site. Because there are billions of sites on the Internet today, trying to monitor all of the sites in which youlve invested advertising dollars and the sites that you have built partnerships with, makes for a tough job. It is a daunting task trying to keep track of all the advertising links, banner ads and your link exchange partnerships that have accumulated over time.
